' tion.

This invention relates to an improvement 1n pumps adapted to pump air water or any other material, the object of the invention being a pump which will work with little friction, and which will therefore be easy of operation and of great durability.

T he invention consists of the pump shown in. its preferable embodiment in the drawings accompanying and forming part hereof and hereinafter described and claimed.

In the said drawings:

Figure 1 is a vertical central section of a pump constructed in accordance with my invention.

Figure 2 is a vertical section at right angles to that shown in Figure 1.

Figure 3 is a perspective detail.

Figure 4c is a perspective view of a disk.

Referring now to the details of the drawings by numerals: 1 designates a casing closed at opposite ends by heads 3 and ihavstufling boxes 6 and 8 through which passes the driving shaft 10 to which power may be applied as by a pulley 12. The cas- Il is supplied with an inlet 14: and an outlet 16.

Each of the heads 3 and 4 is provided with an internal hub as 20 within which the aforesaid shaft 10 rotates. Said hubs 20 are spaced apart at the center to receive a dish 22 which is keyed to and revolves with said shaft 10 between said hubs 20.

This disk has formed integral therewith a plurality of arms 24, as shown in Figure 4. the drawing showing three such arms on each side of said disk, said arms extending from the disk to the cylinder heads. therefore be understood that said arms must rotate with said disk, and to this end their outer surfaces are formed on an arc of the same diameter as that of the casing 10 whereby friction will be decreased and the arms more easily moved around the casing as said shaf l0 and the disk 22 rotate within said casing.

To each of said arms as is hinged a curved it will wing 26 which in turn is supported by a rings rotatable upon the hubs 20. iherc are preferably five rings on each side of the risk 22. two of these rings 28, 28 being connected to one wing, two others (29, 295 to another wing, and. one central wider ring i connected to the third wing, these rings being preferably spaced by thinner rings 32. If desired anti-friction bearings 34: may be provided between said rings 28 to 30 and the hubs 20. it will thus be seen that each arm and its wing 26 forms a pocket for the material to be pumped as said parts are rotated vithin the casing, the arms and wings athering the material in at the bottom of its movement as shown in Figure 1. and discharging it at the top, the wings 26 drawing in between the rings 28-30 and the right hand side of the casing 1 as shown in Figure 1.

I also desire to call attention to the fact that the wings 26 are also formed'on an arc of the same curvature as that of the interior of the casing so that said wings will snugly against said casing on the right side thereof as viewed in Figure 1, and form an effectual seal.

From the foregoing and the accompanying dr wing it will be seen that I have consti icted very simple pump which will work wi h little friction, which will be easy of operation. and very durable in use.

What I claim as my invention is:

i. In a device of the character described, a casing closed at opposite ends by heads, and having an inlet and outlet, each head provided with an internal hub eccentrically located thereon in combination with a shaft extending concentrically through the heads and eccentrically through the hubs, a disk keyed on the shaft between the hubs the dish having outwardly projecting arms fixed on opposite sides thereof, said arms in stag gored relation on the opposite sides of the disl" he outer surfaces of these arms formed on an arc of the same diameter as the internal bore of the casing, wings hinged to these arms rings carried by the wings in position to surround the hubs these rings spaced apart on the dfferent wings approximately the width of a ring and spacing rings filling the spaces between the rings carried by the wings.

2. In a casing of the character described,

g? neat-nee casing, said arms on one side 01"? said ('sl' being in staggered relation to those upon the OPPOSlte side of the disk.

3. In a device of the character described, the combination of a casing having an inlet and outlet and formed with interior hubs, shaft, a disk rotatable with said shaft, arms formed on and rotatable with said disk,

rings rotatable on said hubs, and wings hinged to said arms and to the said rings. l. in a device of the character described,

the combination ot a casing having; inlet said hubs, arms formed on and rotatable with said disk and located upon opposite sides thereof, rings rotatable upon the hubs of: said casing upon opposite sides of said. disk, and wings hinged to said arms and to said rings.

6. In a device of the character described, the combination of a casing having; inlet and outlet and interior hubs, a shaft rotatable in said casing within said hubs, a disk rotatable with said shaft and located between said hubs, arms formed on and rotatable with said disk and located upon opposite sides thereof, rings rotatable upon the hubs of said casing upon opposite sides of said isk, and Wings hinged to said arms and to said rings, said arms being formed on an arc oi the same diameter as that of the casing. 7. in a device of the characte described, the combination of a casing ha and outlet and formed with lnte shaft, disk rotatable with saiil shaft, a formed on and rotatable with said disk, rings rotatable on said hubs, and wings hinged to said arms and the said rings, said arms and said wings being formed on arc of the same diameter as that oi? the casing. i I

v 8. in a device of the character described,

the combination Oil? a'casing having inlet and outlet and interior hubs, a shaft """atable in said casin within said hubs, a disk rotatable with said shaft and located between said hubs, arn'is formed on and rotatable with said dislc and located upon opposite sides thereof, rings rotat vie upon hubs of said casing upon opposite s des oi? said dish, and wings hinged to sa arms and to said rings, said arms and said i being forn'ied on an arc of th same diameter that of the casing.

The combination with a casing; having an inlet and an outlet, and provi ed with heads securely bolted thereto, sa 2, heads having hubs eccentricto the inner wail of the casing, and a shaft extending; through the centers of the heads and eccentric with respect to the hubs, a disl: internos i tween the hubs and keyed to the ssh arms secured to the disk andcxtend ng in onposite directions, wings hinged to the arms. and rings hinged to the wing and snr ind ing the eccentric bulbs with bear between the rings and hubs. N V

in testimony whereof: I my sin; in presence of two witnesses.
